Agave verschaffletii minima is a diminutive cultivar of Agave potatorum. I was told by the grower that it would get only about a foot across. The type species gets to 2 to 3 feet across and comes from Oaxaca and other nearby states in Mexico.
     This little guy is just a seedling a few inches across. It got hurt over winter and lost a lot of leaves. Hopefully it will come back. It stays potted till big enough to go in the garden.
